Anticonvulsant Meds and Suicide Risk

JAMA — Abstract: Anticonvulsant Medications and the Risk of Suicide, Attempted Suicide, or Violent Death, April 14, 2010, Patorno et al. 303 (14): 1401

Results: The study identified 26 completed suicides, 801 attempted suicides, and 41 violent deaths in 297 620 new episodes of treatment with an anticonvulsant (overall median follow-up, 60 days). The incidence of the composite outcomes of completed suicides, attempted suicides, and violent deaths for anticonvulsants used in at least 100 treatment episodes ranged from 6.2 per 1000 person-years for primidone to 34.3 per 1000 person-years for oxcarbazepine. The risk of suicidal acts was increased for gabapentin (hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.11-1.80), lamotrigine (HR, 1.84; 95% CI, 1.43-2.37), oxcarbazepine (HR, 2.07; 95% CI, 1.52-2.80), tiagabine (HR, 2.41; 95% CI, 1.65-3.52), and valproate (HR, 1.65; 95% CI, 1.25-2.19), compared with topiramate. The analyses including violent death produced similar results. Gabapentin users had increased risk in subgroups of younger and older patients, patients with mood disorders, and patients with epilepsy or seizure when compared with carbamazepine.

Conclusion: This exploratory analysis suggests that the use of gabapentin, lamotrigine, oxcarbazepine, and tiagabine, compared with the use of topiramate, may be associated with an increased risk of suicidal acts or violent deaths.

Combination Therapy for Crohn’s

Better Treatment Found for Crohn’s Disease – BusinessWeek

The international trial included 508 people with Crohn’s disease who had never been treated with immunosuppressive drugs. One-third were given infliximab alone, one-third received only azathioprine and one-third were treated with both. The trial was funded by Centocor Ortho Biotech, which markets infliximab, and Schering-Plough.

After 26 weeks, 56.8 percent of those getting combination therapy had complete remission of symptoms, compared to 44.4 percent of those getting only infliximab and 30 percent of those getting only azathioprine.
